Title: Control device for brakes
IPC: B60T13/14
Filed: 1935-12-21
Abstract: 472,620. Fluid - pressure brakes. COATALEN, L. Dec. 21, 1935, Nos. 35465 and 35466. Void. Convention dates, Dec. 22, 1934 and July 12, 1935. [Class 103 (i)] Hydraulic brake comprises a low pressure pump 8 and an accumulator 14 adapted to supply a large quantity of fluid to take up slack in the brake transmission 7 and a high-pressure pump 9 adapted to apply pressure to the brakes. A cylindrical slide valve contained in a casing 6 and operated by a pedal 1 is adapted to connect the two pumps by pipes 19, 13, to the pipe 7 when the brakes are applied. A check valve 18 prevents back flow from the high-pressure pump into the accumulator. When the pedal is released, fluid is allowed to return from the pipe 7, by the pipe 33 to the reservoir 10. In a modification, the high-pressure pump is also provided with an accumulator and is connected to the valve 6 at 28, Fig. 5. The fluid from the low-pressure pump and accumulator is admitted to the brakes by groove 36 in the piston valve 23 operated by the brake pedal, when this valve is level with passage 47, When the fluid attains a certain pressure it passes by passages 48, 50 below a valve 43 which it raises and admits fluid from the high-pressure pump and accumulator to the brakes. The fluid pressure also acts beneath the driver-operated valve 23 to give a graduating action. In a further modification, the high-and low-pressure pumps circulate fluid through the driver's valve and a reservoir. The driver's valve is a ball operated through a spring and is adapted to stop the circulation and byepass the fluid to the brakes. In a modification of this arrangement this fluid is byepassed to cylinders which through a lever operate cylinders of a hydraulic transmission. The pivot of the lever carries a hand lever for emergency hand control. Both high-and low-pressure pumps comprise a cylindrical slide valve adapted to be moved by the fluid from the pump output when this fluid attains a certain value.

Title: Document feeding and reading apparatus
IPC: G06K13/08
Filed: 1969-07-15
Abstract: 1,235,578. Feeding and delivering sheets. ING. C. OLIVETTI & C., S.p.A. 15 July, 1969 [30 July, 1968], No. 35664/69. Heading B8R. A document feeding device, particularly for feeding documents imprinted with coded symbols in magnetizable ink to a reading apparatus 50, 54, 55, comprises a number of driven rollers 17, 18 19 for moving the document along a feed path, and a number of freely rotatable rollers 22, 23, 24 which normally have their spindles skewed obliquely with respect to the feed path so as to urge the document transversely of the path against a reference surface 1, the spindles being resiliently biased into the skewed position so that the reaction by the document on the rollers 22 . . . 24 moves the spindles until they are substantially perpendicular to the feed path when the document is fully against the surface 1. As described, the surface 1 is horizontal and the document is manually inserted between vertical guides 2, 3, the space between which is decreased in the region of the rollers 17 ... 19. A thin flexible strip 16 is attached to the base of the insertion opening and is slightly raised at its right-hand end to prevent possible jamming during insertion of a document. Insertion of a document interrupts a beam of light from a lamp 14 to a photo-electric cell 15 causing brief energizing of an electromagnet 8 which moves a roller 5 into engagement with a driven roller 13 to feed the document forward to the rollers 22, 17 &c. The spindle of the roller 22 is carried by a fork 28 having a pivot 80 slidable and rotatable in a fixed block 25. A spring 37 urges the spindle into a position, determined by stops 40, 43, where it is oblique to the driven roller 17 with which the roller 22 co-operates, so that the roller 22 moves the document transversely towards the surface 1. A resilient plate 46 engages the end of the pivot 80 to press the roller 22 against the roller 17. The rollers 23, 24 are mounted similarly. When the document engages the surface 1, it tends to move the rollers 22 ... 24 into positions parallel to the feed path thus avoiding damage to the document edge due to prolonged pressure against the surface 1. The surfaces of the rollers 22 . . . 24 have a greater coefficient of friction than the surfaces of the rollers 17 ... 19. A belt 49 carries the document past the reading devices 54, 55 to delivery apparatus. Delivery apparatus.-A document leaving the drum 50 of the reading apparatus is moved by a driven band 64 into a pocket between a fixed plate 61 and a movable presser plate 66. The plate 61 is bent at the entry end to facilitate the entry of the document and co-operates with a guide 60. The plate 66 is carried by a sliding rod 69 at one end and has a wheel 67 at the other end resting on the surface 1. A spring 70 biases the plate 66 towards the plate 61. A movable end wall 71 is adjustable according to the length of the document.
